The primary objective of this study was to employ Darden's store patronage model in order to investigate the role that shopping orientation and store attributes play in store patronage. The study sample consisted of 340 female university students residing in Seoul. The data was analyzed by using path analysis and factor analysis. The recreational shopping orientation played a greater role in influencing the importance of store attributes than did the convenience shopping orientation. Recreational shoppers want a variety of brands and convenience shoppers can be attracted by a convenient location and availability of parking. Six important store attributes(variety of products and price level, proximity, variety of trendy brands, store decor, sales promotion, sales personnel) have a differential influence on store patronage. Shopping orientation was a direct predictor of patronage behavior and mediated the relationship between shopping orientation and store attribute importance. The finding indicated that both the recreational shopping orientation and convenience shopping orientation can be used effectively to position store patronage in such a way as to provide a strong means for shoppers to satisfy their needs. The findings of this study demonstrated that South Korean female shoppers with different shopping orientation have different store attribute preference and store patronage. The results provide a basis for building a successful strategy to attract shoppers and generate sales. The study focused on a specific product category, i.e., women's apparel. To meet the needs of female apparel shoppers, further research is needed to learn more about the distinctive characteristics of Korean consumers that could be applied to a variety of jobs, ages and living areas.

The excavation works for deep foundation in urban areas have recently increased complaints of blasting vibration and settlement of ground level. Foundation must be excavated approximately up to 24-28m depths from the surface. The roads and subway line pass through the excavation area. The Dae-chung station is also located at the nearest distance 5-35m from the working site. To protect subway station and adjacient some structures from blasting and settlement, the level of ground vibration, displacements and stress were monitored and analyzed. The results can be summarized as follows ; 1. An empirical particle velocity equation were obtained by test blasts at Nassan Missi 860 Office tel construction site. $V{\;}={\;}K(D/\sqrt{W})^{-n}$, where the values for n and k are estimated tobe 0.371 and 1.551. From this ground vibration equation, the max. charge weight per delay time against distance from blasting point is calculated. Detailed blasting method is also presented. 2. To measure the horizontal displacement in directions perpendicular to the borehole axis, 6 inclinometers installed around working sites. The displacement at the begining was comparatively high because the installation of struts was delayed, but after its installation the values showed a stable trend. Among them, the displacement by 3 inclinometers installed on a temporary parking area showed comparatively high values, for example, the displacement measured at hole No. IC-l recoded the max. 47.04mm for 6 months and at hole No. IC-2 recorded the max. 57.33mm for 7 months. So, all of these data was estimated below a safe standard value 103mm. 3. Seven strain gauge meter was installed of measure the magnitude and change of stress acted on structs. The measured value of maximum stress was $-465{\;}kgf/\textrm{cm}^2,{\;}-338.4{\;}kgf/\textrm{cm}^2,{\;}302.3{\;}kgf/\textrm{cm}^2$ respectively. In compareto the allowable stress level of steel, they are estimated to be safe.

This investigation aims to provide basic data for rural village planning and rehabilitation planning. Public infrastructures of forty selected villages have been surveyed. Provision of facilities, user satisfaction, perceived problems, and conditions of maintenance have been surveyed for three classified types of infrastructures; 1) public utility spaces such as community hall, and parking lots, 2) public production infrastructures such as warehouses, and irrigation facilities, and 3) public infrastructures for living environments such as roads, water supply, and sewage system. All twenty smaller villages (ki-cho-ma-ul) had problems of poor conditions and insufficient spaces with community halls. Most of the smaller villages suffered from lack of public production infrastructures, or had problems of insufficient spaces and poor maintenance conditions. They also lacked good access roads with adequate right of ways. Only three villages were provided with sewage systems. In the twenty larger villages (myun-bo-ma-ul), though public utility spaces were provided for most of them (as an example, sixteen villages had welfare centers), they were not large enough and they were maintained in poor condition too. On the one hand twelve of the larger villages had farm machine service centers, only a few villages were equipped with warehouses. Many more public infrastructures for living environments were found in larger villages. However, only a few villages had pollution control facilities. Multidimensional scaling revealed groups of distinctive characteristics, in terms of public infrastructures, among smaller villages. It did not show any noticeable distinctions among larger villages.

본고는 댐호수가 제공하는 휴양가치가 댐특성의 변화에 의해 어떻게 달라지는지를 추정하고자 하였다. 이 목적을 위해 실제로 댐방문행위를 분석할 수도 있으나 이 경우 주요 특성변수의 추정이 불가능하거나 어렵고 변수들간의 독립성도 약하여 통계적으로 의미있는 추정결과가 나타나기 어려운 경우가 있고, 따라서 본 연구는 대안으로 선택실험을 실시하여 수질과 수량 및 기타 특성변수의 경제적 가치를 도출하고자 하였다. 선택실험자료를 이용한 추정결과를 10개 주요 댐호수의 선택문제에 적용하여 다양한 시나리오별 특성변화의 경제적 가치를 도출하였다. 분석결과 수질이 특히 민감하게 휴양가치에 영향을 미치는 것으로 나타났고, 수질이나 환경에 부의 영향을 주도록 지나치게 큰 댐을 짓거나 유람선 운행 등을 할 경우 오히려 휴양가치가 감소할 수도 있음이 보여졌다. 모든 댐의 수질이 1등급 개선될 경우 휴양객들은 자신이 댐 1회 방문을 위해 평균적으로 지불하는 비용 이상의 편익을 추가로 얻는 것으로 나타났다. 댐과 관련된 교육홍보관 운영, 댐 인근 및 댐호수 지역의 여타 레크리에이션 기회의 증가도 통계적으로 의미있는 정도로 휴양편익증가에 기여하는 것으로 나타났다.

The purposes of this study were to a) examine using status, b) measure the service quality attributes, c) analyze IPA and customer satisfaction, d) develop the LSM(Local Store Marketing) by location of K theme restaurant such as residential type(A), complex type(B) and downtown type(C). The questionnaires were handed out to 346 of 450(usage rate 76.9%). The statistical data analysis was completed using SPSS(ver 12.0) for descriptive analysis, $X^2$, t-test, ANOVA, reliability analysis, factor analysis, multiple linear regression. From an analysis on service quality attributes, most importance of service quality attributes was more highly perceived than performance of those, except for 'attractive exterior', 'variety of kid's menu', 'convenient facilities for kid' and perceived importance and performance were also significantly different by location of branch restaurant. The attributes to be improved were 'convenience of restaurant's parking lot', 'food tast', 'speedy service' and 'service competency' as branch A(residential type) restaurant, 'convenience of the restaurant location' as branch B(complex type) restaurant and 'convenience of the restaurant location' and 'speedy service' as branch C(downtown type) through IPA analysis. The Overall customer satisfaction was 3.74 and service quality factors had significant effect on overall customer satisfaction. Location of restaurant, which gives a great effect on its operation and marketing, has a important correlation with success or failure of restaurant business enterprises. Therefore, marketing strategy by restaurant location should be developed.
